MACHINE FOB SETTING SNAP-FASTENERS ON: GAKMENET S.

Application filed May 28,

T 0 all whom it may concern.

Be it known that we, IsADoR Wonunm and ADoLPH KoHL, citizens of Austria and United States, respectively, residing at Cleveland, in the county of- Cuya11oga=and State of Ohio, have invented certain new and useful Improvements in Machines for Setting Snap-Fasteners on Garments, of which the following is a specification- This invention relates to machines for setting snap fastenerson garments or the like, the setting being effected by means of staples driven through they fastener and into the garment. These fastenersusu'ally include a base having a rounded head, the base being provided with four holes by which the fasteners are ordinarily sewed onto the garment. By means of the present machine. the fasteners can be stapled on the garment in much less time and at much lower cost.

The machine includes means for feeding staples from opposite sides to a position un der a plunger which drives the staples through the holes in the snap-fastener, and through the garment, and clenches the staples thereunder. Means are provided for feeding the fasteners and also for feeding the staples, both feeds being automatic with the operation of the machine.

In the accompanying drawings Figure 1 is a plan of the machine. Fig. 2 is a section on the line 2-2 of Fig. 1. Fig. 3 is afront elevation partly in section on the line 33 of Fig. 2. Fig. 4 is a detail in section on the line 44 of Fig. 2. Fig. 5 is a detail'of the plunger.

The machine includes a base A which may be mounted on any suitable support, and

this base has a head '6 on which slides a feeder plate P which moves in an undercut groove in the head. '13 is an arm which swings up and down-011 a hinge at 7 and is normally lifted by the spring N. The rear end-of the arm is connected by an adjustable link X, pin E, link L, adjusting screw K, link WV and pin 8 to a lever 9 which is pivoted at 10 in the frame of the machine, the upper end of the lever engaging a rounded opening in the feeder plate P. l/Vhen the arm B is swung up the action causes the lever 9 to retract the feeding plateP, and

when the arm B is swung down, the same connections advancethe plate P, to carry one of the fasteners to setting position.

The fasteners are contained in a tubular magazine 11, depending from the head 6,

where they are retained in proper alinement by being threaded on two or more wires 12 which pass through the holes in the'fasteners, andthe fasteners are fedupwardly from the magazine by a. spring 13 which may be adjusted by a screw 14: working through the bottom of the magazine. The magazine is supported by a plate 15, bracket 16, and

dowel pin17, fixed to the overhang of the head 6.

The clenching die 0 sets in a socket in h ip t ntof he he lan c -j p ra s th a p u ger T h hw rk i a recess in a casing 20j at the front end of by a cam E on a andle D which is pivoted at 21 to the upper end of the casing 20.

A small fiat plate 22 is supported by a spring 23 againstthe underside of the feeder plate P, and acts as abridge which prevents the fastener from dro ping out of the hole 24 in the feeder plate P as the plate advances The staples are advanced by sliding blocks N connected by cords F to spring rollers G also mounted on the arm,'the cords being guided over small wheels Q, and the rollers being actuated by coil springs V inclosed inthe rollers and connected at one end to the rollers and at the other end to the pins 28 on which the rollers'turn, after a fashion ofa shade roller;

In operation the arm B is lifted or swung up on its pivot 7. This opens the mouth of the machine and permits the edge of the garment J to be inserted over the die, and also retractsthe feeding plate P until its opening. 24 is in line with the magazine. The spring in the magazine lifts the upper fastener 30 into said opening, where it is stopped by a shoulder around the opening. At the same. time the staples are fed inwardly against the sides of the guide R, under the prongs 19 of the plunger T. The arm B is then swung down and registers the plunger with the opening inthe plate P, which plate in the meantime is advanced to carry the fastener into position over the from the magazine to the setting position.

which the branches 19 of the plunger'work.

die. The handle D is then swung down and the cam forces the plunger T downwardly and its prongs 19 engage the top of the staples and force said staples down through the holes in the fastener and through the garment below and against the die O by which they are clenched. The garment J can then be slid along to the next position,

if a row of fasteners are to be attached, and

the operation repeated. 7 p

The invention is not limited to the exact form shown, but various modifications may be made within the scope thereof.

e claim: 1

1. The combination of a clenching die, a swinging arm, a pair of staple guides carried by said arm at opposite sides thereof, a plunger carried by the arm and swinging therewith toward and from the die, and adapted to force staples from said guides through the work and against the die, means carried by the arm to feed staples to each of said guides, and means carried by the arm to advance the plunger with respect to the arm. I I

2. The combination of a clenching die, 7

staples through said fasteners and work and against said die, comprising a plunger carried by the arm, and a cam lever pivoted on the arm and engaging the plunger to advance the'same, said lever also forming a handle to swing the arm.

In testimony whereof, we do aflix our signatures in presence of two witnesses.
